Hey Michael! The literature on “Framing even small contributions as helpful for achieving charitable aims” (referred to as ‘Legitimizing Paltry contributions’/‘LPC’ in the literature ) suggests that the technique leads to similar contributions overall.
“To conduct this analysis, we calculated total donation amounts for both experimental and control groups from 10 research reports representing 18 comparisons (U.S. samples only) and a total of 2,054 participants. Care was taken to ensure donation totals were adjusted to reflect an equal number of participants in the LPC and control conditions for each study. Because our observations of these data were at the study level (e.g., total amount contributed in the LPC and control conditions), it was not possible to use traditional meta-analytic techniques to test for differences. Instead, we examined differences using a paired t test with the experimental and control condition donation totals from a given study each representing one data point. The difference between the donation totals for experimental (M = 49.07, SD = 49.68) and control conditions (M = 46.04, SD = 57.01) was not statistically significant, t(17) = .41, p = .69 (two-tailed).”
Here is their summary of related prior research:
“The results from studies that have examined the effects of LPC on donation size are mixed. Whereas the findings from some research reports show that legitimizing paltry contributions decreases donation amounts (e.g., Reeves et al., 1987; Shearman & Yoo, 2007), others show that the tactic does not affect charitable contributions (e.g., Cialdini & Schroeder, 1976; Weyant, 1984; Weyant & Smith, 1987) or even increases them (e.g., Dolinska & Dolinski, 2014; Dolinski et al., 2005).”
Were you able to get the net effect on total donations?
